Recently, we discovered a novel synergistic induction of cell death by combining sorafenib, the only routinely used palliative chemotherapeutic agent, and the triterpenoid oleanolic acid (OA). However, the underlying mechanisms of action have remained obscure. Here, we report that sorafenib and OA acted in concert to trigger mitochondria-mediated apoptotic cell death, which is dependent on reactive oxygen species (ROS). Sorafenib/OA cotreatment significantly increased ROS production, which was prevented by the ROS scavengers α-tocopherol and MnTBAP. Importantly, rescue experiments showed that ROS were required for sorafenib/OA-induced apoptosis as ROS scavengers protected HCC cells against cell death. In addition, sorafenib and OA cotreatment cooperated to decrease myeloid cell leukaemia-1 expression and to activate Bak, two events that were prevented by ROS scavengers. Bak activation was accompanied by the loss of mitochondrial membrane potential, followed by PARP cleavage, DNA fragmentation and, finally, apoptotic cell death in HCC cells. By providing new insights into the molecular regulation of sorafenib/OA-mediated and ROS-dependent cell death, our study contributes toward the development of novel treatment strategies to overcome sorafenib resistance in HCC. 000163644 536__ $$0G:(DE-HGF)POF3-899$$a899 - ohne Topic (POF3-899)$$cPOF3-899$$fPOF III$$x0 000163644 588__ $$aDataset connected to CrossRef, PubMed, 000163644 650_7 $$2NLM Chemicals$$aAntineoplastic Agents 000163644 650_7 $$2NLM Chemicals$$aReactive Oxygen Species 000163644 650_7 $$06SMK8R7TGJ$$2NLM Chemicals$$aOleanolic Acid 000163644 650_7 $$09ZOQ3TZI87$$2NLM Chemicals$$aSorafenib 000163644 650_2 $$2MeSH$$aAntineoplastic Agents: pharmacology 000163644 650_2 $$2MeSH$$aApoptosis 000163644 650_2 $$2MeSH$$aCarcinoma, Hepatocellular: drug therapy 000163644 650_2 $$2MeSH$$aCarcinoma, Hepatocellular: metabolism 000163644 650_2 $$2MeSH$$aCarcinoma, Hepatocellular: pathology 000163644 650_2 $$2MeSH$$aCell Proliferation 000163644 650_2 $$2MeSH$$aDrug Therapy, Combination 000163644 650_2 $$2MeSH$$aHumans 000163644 650_2 $$2MeSH$$aLiver Neoplasms: drug therapy 000163644 650_2 $$2MeSH$$aLiver Neoplasms: metabolism 000163644 650_2 $$2MeSH$$aLiver Neoplasms: pathology 000163644 650_2 $$2MeSH$$aMembrane Potential, Mitochondrial: drug effects 000163644 650_2 $$2MeSH$$aMitochondria: drug effects 000163644 650_2 $$2MeSH$$aMitochondria: metabolism 000163644 650_2 $$2MeSH$$aMitochondria: pathology 000163644 650_2 $$2MeSH$$aOleanolic Acid: pharmacology 000163644 650_2 $$2MeSH$$aReactive Oxygen Species: metabolism 000163644 650_2 $$2MeSH$$aSorafenib: pharmacology 000163644 650_2 $$2MeSH$$aTumor Cells, Cultured 000163644 7001_ $$aHinrichs, Tobias M$$b1 000163644 7001_ $$aLange, Matthias$$b2 000163644 7001_ $$0P:(DE-HGF)0$$aFulda, Simone$$b3 000163644 773__ $$0PERI:(DE-600)2025803-3$$a10.1097/CAD.0000000000000750$$gVol. 30, no. 3, p. 209 - 217$$n3$$p209 - 217$$tAnti-cancer drugs$$v30$$x0959-4973$$y2019 000163644 909CO $$ooai:inrepo02.dkfz.de:163644$$pVDB 000163644 915__ $$0StatID:(DE-HGF)0410$$2StatID$$aAllianz-Lizenz$$d2020-01-03$$wger 000163644 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz$$d2020-01-03$$wger 000163644 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bANTI-CANCER DRUG : 2018$$d2020-01-03 000163644 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2020-01-03 000163644 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2020-01-03 000163644 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database$$d2020-01-03 000163644 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2020-01-03 000163644 915__ $$0StatID:(DE-HGF)1110$$2StatID$$aDBCoverage$$bCurrent Contents - Clinical Medicine$$d2020-01-03 000163644 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index$$d2020-01-03 000163644 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2020-01-03 000163644 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded$$d2020-01-03 000163644 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2020-01-03 000163644 915__ $$0StatID:(DE-HGF)1190$$2StatID$$aDBCoverage$$bBiological Abstracts$$d2020-01-03 000163644 915__ $$0StatID:(DE-HGF)1030$$2StatID$$aDBCoverage$$bCurrent Contents - Life Sciences$$d2020-01-03 000163644 915__ $$0StatID:(DE-HGF)1050$$2StatID$$aDBCoverage$$bBIOSIS Previews$$d2020-01-03 000163644 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5$$d2020-01-03 000163644 9141_ $$y2019 000163644 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-HGF)0$$aDeutsches Krebsforschungszentrum$$b0$$kDKFZ 000163644 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-HGF)0$$aDeutsches Krebsforschungszentrum$$b3$$kDKFZ 000163644 9131_ $$0G:(DE-HGF)POF3-899$$1G:(DE-HGF)POF3-890$$2G:(DE-HGF)POF3-800$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bProgrammungebundene Forschung$$lohne Programm$$vohne Topic$$x0 000163644 9201_ $$0I:(DE-He78)L501-20160331$$kL501$$lDKTK Frankfurt$$x0 000163644 980__ $$ajournal 000163644 980__ $$aVDB 000163644 980__ $$aI:(DE-He78)L501-20160331 000163644 980__ $$aUNRESTRICTED
